LAFAYETTE — The field for the Lafayette City Golf Championship learned something during Sunday’s final round.

Give David Duhon a lead heading to his home course, and he’s hard to beat.

Duhon blazed to a bogey-free 5-under-par 67 Sunday at Hebert Municipal, adding to his first-day lead and allowing him to coast to his second city title by a six-stroke margin.

The City Championships rotate annually among two of the city’s three municipal courses, and Duhon’s 1-under 71 Saturday at The Wetlands was enough for a two-shot lead over the field.

“I felt really good coming back to Muni,” Duhon said after posting five birdies and not really threatening a bogey despite the intermittent rain and breezy conditions. “I grew up here. I’ve been playing here since I was 12. It was nice coming here with the lead, knowing the course like I do.”

Duhon won his first city title in 2007, and that year the event also held its final round at the venerable 6,200-yard Hebert layout. Duhon also took that title by six strokes, but his scores were even better this year as he threw his 71-67—138 mark at the 20-man championship flight.

Two other familiar names also claimed honors on Sunday’s final day of the 36-hole event sponsored by Lafayette Consolidated Government. Lauren Aillet, the runaway ladies’ division leader after an opening 70 at The Wetlands Saturday, added a 2-over 74 for an even-par 144 total and a huge 34-stroke win for her second city title after winning in 2012.

John Broussard, the leader by five strokes after Saturday’s opening round in the seniors (age 62 and over) division, added a 2-over 74 Sunday and won his second straight seniors title by a three-stroke margin over Bill Kallam. Stan Andrews was the other individual winner, taking the open flight in a scorecard playoff with Roy Vanhaverbeke and first-day leader Donnie Chauvin.

Duhon finished with five birdies Sunday and never had a par putt of more than four feet.

“There were three or four holes that I had to get up and down,” he said, “but I chipped it really close on most of those. I sort of had a number in mind ... I figured if I could shoot 68, that I could hold on.”

He bettered that, and his only late challenge came from runner-up Buddy Schilling, who was 4-over-par for the tournament with seven holes to go before a late charge. He birdied the 12th, 14th, 17th and 18th holes to card a final-round 69 and finish at even-par 144.

“Too little, too late,” Schilling said.

“I had a good round, just didn’t get anything to drop early.”

The trio of Jody Lormand, Denny Guilbeaux and 2011 city champion Ted Weber tied for third at 148, and 2012 winner Mick Huffman was one more back at 149.

Duhon rolled in a 12-foot putt for birdie on the par-4 fourth and a 15-footer on the par-3 sixth hole, but may have had his best shot of the tournament on the par-5 eighth. His second shot rolled against a root next to the fairway, but his third-shot wedge stopped three feet from the pin for his third birdie on the front side.

“I felt really good after that one,” Duhon said. “I was on a pretty good roll.”

That was just before a clear-the-course horn sounded after Duhon’s final group finished the ninth hole, with rain and lightning creating a delay of just under an hour.

“I didn’t want to stop, no doubt,” he said. “But that probably worked in my favor because I had to focus on the next shot.”

When play resumed, Duhon had a routine par at the par-three 10th hole and scrambled for pars with up-and-downs on three straight holes before rolling in a 15-foot birdie putt on the par-five 14th. He parred in until the 18th, where he knocked a 60-degree wedge to 10 feet and made a final birdie putt.

“This made up for yesterday,” Duhon said after he missed several par putts at The Wetlands Saturday. “The putter felt good, and my tee-to-green felt good. I just felt calm all day.”
